Laser – a perfect starting point for precision measurement
The laser beam is the reference for the measurements. It can be compared to an absolutely straight and weightless ruler, that is to say a perfect starting point for precision measurement. But different measurement applications require different laser transmitters. Read on to learn more!
XT20 and XT22: versatile transmitters with swiveling laser head
These transmitters can handle most types of geometrical measurements, like straightness, flatness, and squareness. The swiveling laser head gives a 360° laser plane parallel to the measured object, and the XT22 can also angle the laser beam 90° to the sweep for squareness measurement. The electronic levels ensure quick feedback and low risk of errors.
Both transmitters connect to the XT Alignment app. This gives you several benefits when it comes to ease of use. The app also warns you of temperature changes and vibrations that can affect the measurement results negatively. Step-by-step guidance during calibration of the units is another advantage.
What are the main differences between these two transmitters? Take a look in the table below.
| XT20 | XT22 | |
|---|---|---|
| Measurement radius | 20 m | 40 m |
| Type of laser | Diode | Fiber-coupled diode |
| Laser head fine turning | 1:132 gear ratio | 1:1320 gear ratio |
| IP Class | IP55 water and dust proof | – |
| Operating time | Up to 30 hours | Up to 30 hours |
| Battery type | Rechargeable Li-Ion | Rechargeable Li-Ion |
| Laser beam | 360° sweep | 360° sweep or 90° angle |
| Electronic precision levels | x | x |
XT24 measures straightness of bores and more
The Easy-Laser® XT24 laser transmitter is typically used to measure the straightness of, for example, bore center lines and propulsion drive lines. The laser transmitter has a measurement distance of up to 40 meters, and brackets are available for many purposes. The fiber-coupled laser diode provides extreme accuracy.
Laser transmitter for sheave and pulley alignment
This transmitter is used to align belt or chain transmissions. The laser transmitter is mounted on one of the sheaves, and the detector on the other. The transmitter generates a laser plane parallel to the reference sheave. The detector reads the position in relation to the laser plane and provides a live digital display of both offset and angular value. This makes the alignment of the adjustable machine very simple. If you connect the detector to a separate display unit, for example your smartphone, you can follow the alignment at the place where you adjust, making the job even easier!
The transmitter and detector are mounted on the sheaves with magnets.
Application examples
Flatness measurement of machine foundation using XT22 with swivel head.
Bore alignment with the XT950 system, which includes the XT24 transmitter.
Alignment of sheaves using the XT190 belt transmission alignment system.
